If they operate on the same frequency range it is no
problem. VHF to VHF or UHF to UHF.

We need to know exactly what frequencies you
have in your current radios.The initial
programming when you buy the radios from Power Works is free. You can either
fax or e-mail us your frequencies and PL Tones or if you do not know
them, you can send us one of your old radios and we will match it with the new
ones. We will send your radio back to you with your new radios.
